“…Comparative analysis of the proposed LED driver with existing topologies is given in Table 1. From the comparison table, it is clear the efficiency of the proposed converter is higher than the converters in other studies, 27–29 which are working on full‐bridge series resonant converter principal. Also, the component count of the presented converter is less than the converters in and Kasi Ramakrishnareddy et al 28 and Veeramallu et al 29 .…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…For automotive lighting applications, BB converter is generally preferred because of wide range of variations in input voltage. BB converters were investigated for automotive applications with 12 V [7], 24 V [8] and 48 V [9]. Yaxiao Q developed a fourswitch noninverting BB converter with 96% maximum 2 efficiency.…”

“…Though, the system has higher efficiency, the voltage gain of the converter is less than unity [8]. A twostage resonant BB LED driver was developed in [7] and full bridge series resonant converter was proposed in [9]. In those topologies, efficiency is maintained constant (93%) for wide range of input variations.…”
